ChainCatcher news, according to the official blog, the IOTA Foundation has announced the launch of the IOTA 2.0 public testnet. This update introduces a decentralized Proof of Stake (PoS) mechanism, replacing the old coordinator-driven system, and eliminates the traditional Proof of Work (PoW) mechanism, enhancing scalability and reducing environmental impact. IOTA 2.0 aims to create a more secure, scalable, and environmentally friendly network, inviting the community to participate in testing and optimizing this process.

ChainCatcher message, BounceBit posted on platform X stating that the BounceBit Chain introduces a dual-token PoS mechanism, allowing users to stake BB and BBTC and earn approximately 15% APR. The official portal now supports native staking, and users can receive stBB and stBBTC.

ChainCatcher news, Ethereum co-founder Vitalik Buterin published an article proposing three methods to simplify Ethereum's proof-of-stake design.The first solution focuses on decentralized staking pools. This would expand the minimum deposit required to run a validating node to 4096 ETH and facilitate the reorganization of validating node resources.The second method is two-tiered staking, where the heavy layer requires a stake of 4096 ETH and participates in finality, while the light layer has no minimum stake requirement (nor deposit and withdrawal delays). These two layers will be treated differently in the block finalization process.The third method is alternating participation (i.e., committees with accountability), which means selecting a random set of validators for each slot. This would distribute the workload and reduce the total number of signatures, but this approach increases protocol complexity. The advantage is that it retains individual staking in a recognizable form, maintains a first-level system, and even allows the minimum deposit size to be lowered to very low levels (e.g., 1 ETH).

ChainCatcher news, NFT infrastructure company Palm Network will migrate from the current Proof of Authority (PoA) consensus mechanism to a Proof of Stake (PoS) mechanism on August 1, and plans to complete the migration to Polygon's ZK Supernet by 2024.

ChainCatcher news, Bitget was invited to participate in the 2023 Hong Kong Web3 Carnival. Bitget's Asset Management Director Zero CHU shared insights during the roundtable discussion on "Staking Economics and Regulation." He pointed out that the POS mechanism of ETH and its immense liquidity will attract investment institutions and family offices to invest in and stake ETH.With the emergence of projects that lower the barriers to staking and new LST gun pools, it is believed that the staking track will spark a new wave of innovation and momentum. The regulation by the U.S. Securities and Exchange Commission does not mean that the crypto community will fall into a passive situation; rather, it will promote communication. Bitget is committed to building its own compliance team to advance licensing matters and is currently actively applying for licenses in places like Hong Kong, while also engaging in proactive communication with regulators.

ChainCatcher message, Solana developer Paul Fidika, who is engaged in Aptos staking development, revealed on Twitter the reasons for stopping his work on Aptos: 1. The Aptos tokens sold by FTX, Coinbase, and Binance have already been owned and staked by the exchanges, with no ICO; 2. Aptos lacks community operation and has no permissionless validators; 3. It employs a false PoS mechanism; 4. It cannot share rights across mining pools; 5. The Aptos BFT V4 version is merely a renaming of the Diem BFT V4 version, using the HotStuff algorithm.

Chain Catcher news, Vitalik Buterin recently stated at the Mainnet conference that all blockchains hoping to scale, such as Dogecoin and Zcash, should follow Ethereum's lead and transition to a Proof of Stake (PoS) consensus mechanism.When asked if similar merging activities would be executed, Zcash founder Zooko Wilcox said, "We have been observing and have realized from the Ethereum merge upgrade that migrating to PoS is really effective."
